Sash-holder.



JOHN E. MALKIN, OF NEW YORK, N. Y.

SASH-HOLDER.

Specification of Letters Patent.

Application filed September 8, 1917. Serial No. 190,294.

' To all whom it may concern:

Be it known that I, JOHN E. MALKIN, citizen of Russia, resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification.

This invention relates to improvements in devices for holding window sashes in an adjusted position, and has as its principal object the provision of means aflixed in appropriate grooves or recesses, formed in the sides of the window sash, the same having projecting resilient elements adapted to engage within the channels formed in the window frame, in such manner as to hold the window sash at any desired height.

A further object is to provide such devices in forms which may be cheaply constructed and easily applied, without material change in the window sash and none what ever in the sash frame.

These and other like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a fragmental front elevational view of an ordinary window indicating the application of the invention.

Fig. 2 is an enlarged fraginental sectional view of a window frame showing the inven tion in an operative position.

In the drawings, the Window frame is indicated by the numeral 10, and the sash 11, containing the window panes 12.

In Fig. 2, a backing plate 15, is secured by screws 16, in the bottom of a groove or recess 17, formed in the sash 11, and to the bottom of the recess of the sash 15, attached by rivets 19, is a flat arcuate spring 20.

Extending through the spring element 20 copies of this patent may he obtained for are a pair of pins 22, screw threaded at their lower ends and passing through an adjusting plate 23 near each end thereof, the plate being movable upon the pins by the nuts 24, for the purpose of adjusting the tension of a coiled helical spring 25, one end of which abuts against the plate and the other against a U -shaped element 27 carrying the loosely journaled roller 28, adapted to make contact with the slideways in the window frame, this type of construction being used with the heavier varieties of window sashes.

From the foregoing, it will be seen that the device may be readily applied to a Window sash as resently described, and that the same is a apted to exert suflicient pressure to hold ordinary window sash in an adjusted position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

In a device of the character described, the combination of a window and its frame, said frame having a channel in one side thereof and a recess provided in said window, a plate secured rigidly in the bottom of said recess, and outwardly bowed springs movably attached to said plate for outward movement toward the open end of said recess, a roller carried by said spring. member and adapted to engage the channel in the window frame, threaded rods, a plate adjustable at each of its ends upon said threaded rods, a nut for adjusting said plate and looking it in said adjusted position, and a spring between the adjustable plate and roller for forcing the roller and spring member outwardly.

In testimony whereof I have afiixed my signature.

JOHN E. MALKIN.
